In the preview of the movie "Summer in That Year" episode 4, Khanh (Long Vu) went to meet Phuong's mother to suggest taking the land use right certificate to his house to borrow money. Khanh whispered to Mrs. Ngoc (Van Dung) that he had secretly looked at the books and learned that his mother lent money at a lower interest rate than the bank. "You just trust me. Just look at my mother and me like that, it's easy to be heartbroken. Today my mother and I just paid off our debts, we have money ready. You just come over, it's always available," Khanh affirmed.
When Ms. Ngoc asked why Khanh stole her mother's books, Khanh said that it was like Phuong (Luu Ly) selling goods to help Ms. Ngoc.
When he got home, Khanh sulked at his parents for not helping Phuong's family: "Parents still taught me to live knowing before and after, with affection and meaning, one horse hurts, the whole ship abandons the grass, what else. Parents may not care, pay attention to Phuong's family is okay, but Phuong has been friends with me since childhood, played with each other since childhood, grew up together. He is so sad and miserable, I don't have the mind to eat and drink".
In the evening, Phuong also invited Khanh out to confide. She said she felt very sad because her mother intended to sell the house. Seeing Phuong sad, Khanh comforted her not to be negative and to think about everything in a more positive direction.
